No, both are divisible by 25.
No, 75 and 625 are not relatively prime. No pair of numbers that both end in 5 can be relatively prime.
No, there is no common divisor between 285 and 75. Therefore, they are relatively prime.
It is: 73
No.
No they are not...
No.
yes they are
No, 60 and 75 are not relatively prime because their greatest common factor is 15 and not 1. In order for them to be relatively prime, 1 must be their greatest common factor.
I'm uncertain about what you mean by "relatively", but 75 and 99 are not prime. Factors of 75: 1, 3, 5, 15, 25 and 75 Factors of 99: 1, 9, 11 and 99
125
50% of number is 75 1% of number is 75/50 Therefore 100% of number (which would be the number) is (75/50) x 100 = 150
